Stagnant slabs at the transition zone linked to widespread volcanism in Eastern Australia and Zealandia

Partial melting of ancient subducted slabs provide a framework through which to explain non-age progressive volcanism in a region of anomalous mantle composition.

The origin of intraplate mafic volcanism along the eastern margin of Australia

The eastern margin of Australia has experienced extensive mafic volcanism since its breakaway from Antarctica (~ 80 Ma). A plume origin has been suggested for intraplate volcanism, however, the timing and location of eruption points does not clearly …
